[Problem] To provide a fermented soybean container in which even though extra waste is unlikely to be produced at the time of use and relatively low-cost production is possible, seasoning for fermented soybeans stored in the fermented soybean container can be easily discharged without contaminating surrounding areas.[Solution] A fermented soybean container (11) of the present invention has a structure in which a container body (22) made from resin foam and having a fermented soybean storage concave portion (25), and a lid body (23) covering an opening (26) of the container body (22) are coupled via a hinge portion (24). The lid body (23) is provided with seasoning storage concave portions (32) formed so as to protrude to a lid body inner surface (23b) side. A fold-scheduled line (L1) for folding the lid body (23) inward to a lid body outer surface (23a) side is set on the lid body (23). The lid body (23) is provided with a cleavage groove (31) that is communicated with the seasoning storage concave portions (32) across the fold-scheduled line (L1). A seal member (13) for covering and sealing openings of the seasoning storage concave portions (32) is provided on the lid body outer surface (23a) side. When the lid body (23) is folded inward along the fold-scheduled line (L1), the cleavage groove (31) is cleaved on a fold-scheduled line transverse point (35) of the cleavage groove (31).Linvention concerne un récipient de soja fermenté selon lequel, même si un gaspillage supplémentaire est peu susceptible de se produire au moment de lutilisation et même si une production à un coût relativement faible est possible, lassaisonnement pour le soja fermenté stocké dans le récipient de soja fermenté peut être déversé facilement sans souiller les régions voisines. Un récipient de soja fermenté (11) selon la présente invention présente une structure dans laquelle un corps de récipient (22) composé de mousse de résine et comprenant une partie concave de stockage de soja fermenté
